APPARATUS non cnosme AND SEALING RECEPTAGLES.

Application filed August 12, 1922. Serial No. 581,323.

To all whom it may concern:

Be it known that I, IRVING STANLnY,-a citizen of the United States, anda resident of the borough of Manhattan, in the cit county, and State ofNew York, have invented certain new and useful Improvements in Apparatusfor Closing and Sealing Receptacles, of which the following is aspecification.

This invention relates to apparatus for closing and sealing the open endof a receptacle or container made by rolling a sheet into tubular form,preferably of truncated cone shape, and having a closure secured at oneend, the container being made of paper paraflined and especiallvintended for milk or other liquids, although it may be utilized forother purposes, the open end of the receptacle being closed by squeezingor pinching the end together and securing said end in closed conditionby a clamping strip, and it is the object of the invention to provide animproved method and means for applying the sealing strip or member tothe closed end of the receptacle and an improved manner of sealing saidmember to the receptacle.

Various methods have been employed for applying the sealing or clampingmember or strip to the receptacle as by bending a metallic strip aroundthe closed end of the receptacle and severing the same from the strip,or forming a metallic strip to channel shape, feeding such stri over theclosed receptacle end, clamping and sealing the strip to the receptacleand then severing the same from the strip. The sealing member has beenheretofore secured to a receptacle either by stamping prongs from thematerial of the clamping strip and embedding said prongs in the materialof the receptacle, or by perforating the clamping strip and providingseparate means to engage therein for riveting the sealing member to thereceptacle. been found deficient in that in severing the clamping memberfrom the strip after it has been applied to the receptacle it has beenimpossible to sever the clamping member without leaving a rough edgewhich is liableto scratch orcut the hand when handling the receptaclesor in use in tearing the strip from the receptacles to open the same. Itis the principal object of the invention to overcome the abovedisadvantages.

In carrying out the invention the open end However, all of these methodshave.

of the receptacle is collapsed and closed and held in its closedcondition, and while so held a metallic strip is longitudinally bentupon itself to inverted channel shape; a portion of the material is thenstamped from the formed strip to provide a sealing member ofpredetermined length, the stamping of the material therefrom leaving asmooth rdge where it has been severed. The severed strip is thendelivered over the closed end of the receptacle, guiding and gaugingmeans being provided to position the re ceptacle and the sealing memberrelative to the receptacle previous to the clamping of the sealingmember to the receptacle. The receptacle in this condition istransported to die mechanism to stamp a portion from the sealing memberat one side of the receptacle and force such stamped material throughthe material of the receptacle and the opposite side of the strip, whenthe recepta'cle is transported to die mechanism for upsetting suchstamped portions of the strip at the outer side of the portion of thestrip opposite to that from which it has been stamped.

Similar characters of reference designate like parts throughout thedifferent views of the drawings.

In carrying out the embodiment of my invention shown in the drawings Iprovide a table T upon which the operative mechanism is mounted, saidtable being supported by suitable standards, not shown. The reoeptaclesto be operated upon after having 14 is a perspective view of the f beenfilledare delivered to a conveyer consisting of a pair of chains 21having successively mounted thereon in predetermined spaced relationperforated plates 22 to constitute supports for the receptacles. Thesechains pass around sprocket wheels (not shown) at opposite ends of theframework and are intermittently advanced a predetermined distance bysuitable means and in a manner, such for instance, as disclosed in myco-pending application Serial No. 483,- 443 to which reference may behad.

During the periods of rest of the receptacle conveyer a receptacle Rwill be positioned in alinement with means to collapse and close theopen end of the receptacle and to clamp a sealing member theretopreparatory to sealing said member to the receptacle. This meanscomprises a pair of slides 23 (Figures 12 to 14) slidably mounted in ahead H fixed to or integral with a standard 24 fixed upon the table,said head extending from said standard over the conveyer in spaced andalined relation thereto said slides being adapted to have reciproca-torymovement toward and away from each other. The slides 23 carry a pair ofauxiliary slides 25, 26 to participate in the movement of the slides 23and have movement relative thereto. form of a yoke having a stem 27slidably mounted at the bottom of a slide 23 by a cap or plate 28secured to the bottom of the slide. The other slide 26 is arranged toslidably engage within the legs of the yoke of slide 25 and has a stem28 whereby it is slidably mounted at the bottom of the other slide 23 bya plate or cap 29. Each of the slide stems 27, 28 has the end thereofflanged or bent upwardly to engage in a recess 30 in the bottom of theslides 23 whereby the auxiliary slides are adapted to participate in-themovement of the slides 23 and have a limited movement thereof, and arenormally urged forwardly of the slides 23 by springs 31.

The slides are actuated by levers 32 pivotally mounted on stud-s 33 uponthe standard 24 to have movement on vertical axes,

one arm of each of the levers being ivotally connected to studs 34 fixedto an projecting up from each of the slides 23. The levers are actuatedto move the slides to- -ward and away from each other by cams 35,

36 on a shaft 37, the other arms of the levers 32 carrying rollers orcam followers to co-operate with said cams. The cams are so constructedand timed that there will be an initial movement imparted to the slidesand during this movement 'of the slides the auxiliary slides 25, 26 willengage with and collapse or squeeze together the open end of areceptacle and close the same, the receptacle assuming substantially thedotted line position R shown in Figure 5, and sub- The auxiliary slide25 is in the sequent to the closing of the receptacle the auxiliaryslides and the slides 23 are held stationary, the latterserving asguides for a sealing member S as shown in Figure 6, and then later movedtoward the receptacle. During the interim of movement or period of restof the slides 23 after the auxiliary slides have been moved toreceptacle closing position the sealing member is delivered over theclosed end of the receptacle, and subsequent to the delivery of thismember the slides 23 are moved toward the receptacle to clamp saidsealing member to the receptacle preparatory to sealing said member tothe receptacle, this latter movement of the slides 23 being permissibledue to the slidable engagement of the slide flanges in the recessportions 30 of the slides 23 and permitting movement of the slides 25,26 relative to the, slides 23.

To lift a receptacle from a receptacle support of the conveyer andposition the same etween the slides 23, 2526 a support in the form of adisk 38 (Figures 5, 6 and 8) is caused to move through the opening of areceptacle support 22 and engage with and lift the receptacle from theconveyer support and support the receptacle during the period of time itis positioned between the slides. The disk 38 is pivotally connected toa stem or plunger 39 engaging in a bore of a carrier 40 therefor, saidplunger having a portion 41 of reduced diameter to engage in a portionof reduced diameter in the bore of the carrier, the plunger beingnormally urged outward from the bore of the carrier by a spring 42 inthe carrier bore confined be-' tween the shoulders formed by the boreportion of enlarged diameter and the plungerof enlarged diameter, themovement of the plunger being limited by a pin 43 fixed in and extendinglaterally from the plunger engaging in a slot 44 in the carrier. Thecarrier 40 is slidably mounted in a bracket 47 fixed to the table and ispivotally carried, as at 45, by an arm of a lever 46 pivotally carriedat 48 by the bracket 47 the other arm of the lever carrying a camfollowing roller to co-operate with a cam 49 fixed to a shaft 50 toactuate the lever and thereby the plunger, carrier and receptaclesupport carried by the plunger. By the movement of the cam actuated arm46 the receptacles are positioned with the edge of the opening in spacedrelationto a ledge 78 extending transversely of the under surface of thehead H and in which position the sealing member S is delivered over thetop of the collapsed and closed end of the receptacle guided by theledge 78 and the slides 23 as shown in Figure 6.. After the sealingmember has been delivered over the receptacle the receptacle liftingmeans due to the construction and arrangement of the cam 49 is liftedfurther to cause the closed end of the receptacle with the sealingmember thereon to be impinged against the ledge 78 when the slides 23are actuated to abut the sealing member and clamp the same to thereceptacle end, as shown in Figure 9*. Due to imperfections in themanufacture of receptacles it has been found that the edge of theopening of the receptacles is not always horizontal to the axis of thereceptacle, and in order to effect a positive sealing of the receptacleby the sealing member it is essential that the latter embrace the sideof the receptacle, for which purpose the receptacle support 38 ispivotally connected to the plunger to have movement on an axistransverse to the axis of the plunger and transversely of the ledge 78,as clearly shown at 5l, whereby the edge of the receptacle opening iscaused to be gauged against the ledge 78 on the under surface of thehead H. By this arrangement the edge of the opening of the receptacle ispractically squared with said ledge. The yielding or resilient mountingof the support carrying plunger 39 is in the nature of a compensatingdevice for variations in the length of receptacles.

The sealing member S is formed from a metallic strip or web S preferablyin rolled condition 'on a drum rotatably supported, as at 59 in Figure3, and is intermittently fed by a pair of coacting feed rollers 52, 53,the roller 52 being journaled in fixed position in standards 54 mountedon the table and arranged with a peripheral bead 55 of substantiallyinverted V-shape in cross section.

The roller 53 has a peripheral recess 56 complemental to the bead 55 ofroller 52, said roller 53 being mounted on a shaft journaled in blocks57 slidably mounted in slots in the upper portion of the standards 54 tohave adjustment toward and away from the roller 52 and retained inadjusted position by an adjusting screw 58, as clearly shown in Figures1 and 5, the web being directed between the rollers by a guide in theform of a groove in a bracket 60 and retained in such groove by a cap61, or the guide groove may be arranged in the cap 61. The rollers52, 53are intermittently rotated to feed a predetermined portion of the weband simultaneously bend the same longitudinally to channel shape, in thepresent instance substantially to inverted V-shape,'in cross section bya spring influenced pawl 62 pivotally carried at the end of one arm of alever 63 hung or pivotally supported on the shaft ofthe feeding roller52, said pawl co-operating with a ratchet or toothed wheel 64 rotatablethrough a pivotally supported lever 97 carrying a cam following rollerat one end to co-operate with the cam, said lever having a linkconnection 98 with the lever 63. As the arm 63 is moved in one directionthe pawl 62 will engage with a notch or tooth of the ratchet wheel 64and advance the same, and during the retrograde movement of the arm thepawl will ride along said wheel.

The formed strip S is delivered from the feeding and forming rollers 52,53 to a guide 65 and through the latter directed to die mechanism tostamp a portion from the strip and thereby sever a predetermined portiontherefrom to serve as the sealing member. This die mechanism comprises apair of die members 66, 67 fixed in a-lined and spaced relation upon thestandard 24. A movable die member 68 is mounted to have reciprocablemovement in the space between the fixed die members and co-operate withthe latter to shear a portion from the formed strip at a predeterminedpoint from the end to sever a predetermined portion from the strip toconstitute the clamping member and thus assure said severed edge being asmooth and clean-cut edge. The die members 66, 67 are adjustablerelative to each other. ,The die member 68 is carried by a head 69slidably mounted in a bracket 70 by gibs 71, the bracket being fixedupon the standard 24. The die 68 is reciprocated by a cam 72 on shaft 37with which a cam following roller 73 carried intermediate the ends of alever 74 co-operates, the lever being pivotailly mounted at one end uponthe standard 54 the opposite end being bifurcated and engaging a bar 75connected at its ends to rods 76 fixed in the die carrying head 69 andengaging at opposite sides of the fixed die members. The lever 74 isyieldingly urged to position with the cam following roller in operativeengagement with the cam by a spring 7 9. The movement of the feedingrollers and die mechanism is so timedthat the feeding of the strip willbe effected after the open end of a receptacle has been collapsed by theslides 25, 26 and during this movement of said heads the strip clampingand cutting dies are actuated to sever a portion of the strip, whichsevered strip is supported upon the die member 67 and retained thereonby a guide 77 to be engaged by the strip during the successive movementthereof to deliver the severed strip over the top of the closed end ofthe receptacle. After the sealing member has been delivered over theclosed receptacle end the dies 23 are actuated to clamp said member tothe receptacle preparatory to presenting the receptacle to means to fixor seal the member to the receptacle to seal the latter. I

After the sealing member has been clamped to the receptacle the means tolift the re-' ceptacle from the conveyer to present the same to theclosing means is actuated to return the receptacle to its support uponthe the conveyer when the conveyer is actuated to advance the receptacleto the position indicated at R (Figures 2 and 8) and position thereceptacle relative to mechanism for stamping a portion from the sealingmember at one side of the receptacle and forcing such stamped materialthrough the material of the collapsed end of the receptacle and thematerial of the sealing member at the opposite side of the receptacle,as shown iri Figures 10 and 11. This mechanism is arranged on the tablein advanced relation to the receptacle closing means and is mounted upona head H carried by a standard 24 mounted on the table similar to thehead H to extend over the conveyer. This die mechanism comprises a pairof slides 80, 80' the slide 80 carrying a female die, as shown at 81,and the slide 80 carrying a male die in form of punches, as shown at 82,strippers 83, 84 being carried forwardly of said diemembers andyieldingly urged outward therefrom, as shown in Figures 15 to 18 tostrip the receptacle with the clamping member from the die members. Thereceptacle is lifted from a conveyer supporting plate 22 to said diemechanism to engagement with the underside of the head H by means whichis a duplicate of the means for lifting a receptacle from the conveyertopresent a receptacle to the closing mechanism and detailed descriptionof the same is not deemed necessary the same being shown in a generalway at 85 (Figure 2) and is actuated by a cam 49' on shaft 50. The diecarrying slides 80, 80 are reciprocated toward' and away from each otherby earns 86, 87 on shaft 37 through pivoted levers 88, 89 one arm ofwhich levers carry cam following rollers to co-operate with said camsand the other arms being pivotally connected to studs 88', 89 projectingup from the slides 80, 80 and extending through slots in the head H.

After the sealing member has been acted upon to stamp and force aportion of the material of the sealing member from one side of thereceptacle and forcing the same through the closed end of the receptacleand the portion of the sealing member at the opposite side of thesealing receptacle, the receptacle is returned to. a receptacle supportupon the conveyer when the conveyer is again actuated to advance thereceptacle to the position indicated at It (Figures 2, 3 and 8) topresent a receptacle tomechanism to upset such material stamped from theone portion of the sealing member to secure or rivet the sealing memberto the receptacle and thereby securely sealing the receptacle to preventtampering with the contents thereof. This mechanism comprises a pair ofslides 90, 90 the slide 90 carrying pins 91 to engage in the perforatedpunched material to upset such material as shown in Figure 4 at 90, thesame being in the nature of eyelet upsetting members. A stripping plate92 is arranged forwardly of said pins. The slides 90, 90 are slidablymounted in a head H carried by a standard similar to the standard 24mounted on the table sothat the head will extend over the conveyer, andthe slides are reciprocated in a direction toward and away from eachother by cams 92, 93 through pivoted levers 94, 95 carrying camfollowing rollers at one end to co-operate with the camsand the oppositeends pivotally mounted on studs 94, 95 projecting up from the slidesthrough slots in the head H After the stamped material has been upsetthe receptacle is returned to a receptacle support of the conveyer whenthe conveyer is again advanced and the receptacle is removed from theconveyer, the means to lift a receptacle from the conveyer and presentit to said upsetting means and returning the same to the conveyer beingthe same as that described for lifting a receptacle from the conveyer topresent it to the receptacle closing means, the same being shown in ageneral way at 96 in Figure 2.

The mechanism for lifting the receptacles from the conveyer is operativeto simultaneously lift receptacles from the conveyer and present them tothe means to close and clamp thesealing member thereto, the means tostamp a portion from the clamping member, and the means to upset suchstamped material whereby such mechanisms are operating upon receptaclessimultaneously.

The apparatus is driven from a suitable source of power preferablyconnected to the shaft 50 the shaft 37 being driven from shaft 50 by agear 100 on said shaft meshing with a pinion 101 rotatable on a studshaft fixed in the framework, and which pinion meshes with a gear 102fixed to the shaft 37.
